International Standards ISO

Many manufacturers are registered to ISO (International Standards Organization), which is reported to be the toughest industrial quality assurance standards in the world and covers design, development, production, installation, and service. 

ISO. International Standard ISO 1043 1986. Plastics - Symbols and Codes - Part 1 Symbols for basie polymers and their modifieations, and for plasticizers. 

SISO cup constants are from ISO International Standard 2431. k Thermostatted, viscosity units = s/60 mL. 

These sieves correspond to those recommended by ISO (International Standards Organization) as an International Standard and this designation should be used when reporting sieve analysis intended for international publication. 

The ISO (International Standards Organization) suspended sample test (3d), now adopted as MCC-1 by the U.S. Dept, of Energy Materials Characterization Center,(7) and the Sanders static cell test (8,9)(3f) make it possible to control the critical variables needed for kinetics analysis. Addition of tubing to and from the chambers in 3d and 3f is straightforward and enables corrosion to be studied as a function of flow rate.

Among the two genotoxicity tests, the Mutatox is a commercial test using a bacterial strain and is no more difficult to perform than the well known Microtox test. The test on induction of micronuclei in erythrocytes of Xenopus laevis larvae developed by van Hummelen et al. (1989) requires specialized skills and training and is routinely performed only in a few laboratories. However, this test is currently being standardized by ISO (International Standardization Organisation).

To guarantee the quality and the security of the samples and the information derived therefrom by analysis, it will be necessary to establish a strict QA/QC (quality assurance/quality control) program for the GC/MS analysis of chemicals related to the CWC. This program has to be in accordance with an internationally recognized QA standard (ISO (International Standard Organization)) 17025...

Chapter 10 discussed test methods of interest in cellular plastics and related materials from a general point of view and listed industry, government, British and International (ISO) standards in a number of relevant subject areas. This chapter will list published specifications (139) and test methods (116) used in the United States, in addition to British Standards (28) and ISO International Standards (40). United States industry standards inlcude ASTM Test Methods (116), ASTM Practices, Guides, Definitions, Terminologies and Abbreviations (24), ASTM Specifications (23), SAE-AMS Specifications (25), and Underwriters Laboratories Standards (1). U.S. Government standards covered include Military Specifications (67), Military Standards (S), Federal Standards (2), Military Handbooks (6), and Federal Specifications (24). Most of these standards are undergoing frequent revision and unused standards are constantly being withdrawn. A total of 361 standards are covered.
